popauth: unknown userid

[lucas]

Ok, this is strange. I have a FreeBSD 4.2 system, and I have a 'pop' entry in 
the passwd file, UID 68. popauth doesn't think so. When I run popauth -init It 
returns this error:
popauth: "68": userid unknown

I took a peek at the source, and this error is returned upon failure of 
getpwnam. I am not entirely sure if this is a configuration problem within my 
system or if popauth is smocking crack. Does anyone know?
